Ivory white color... is it available for purchase?? RAL number?

Your question did not specify what you wanted to paint with the color; it could have been that you wanted to paint a shelf in the matching color. The example of wall paint is given because so far I have only had wall paint mixed there, but they also mix other paints and varnishes; however, I do not know the prices for those. I do not know if Ädel and Stat are identical; they are very similar, but you would need to compare the two fronts on site. Maybe also inquire at a paint shop; perhaps they can help you further.

That is the color code (NCS), Lidingö and Stat are painted, Ädel is foil.

With paint, there are different gloss levels, and whether you can achieve that with a brush or roller as well as with a spray gun is doubtful.

By the way, foils also have different gloss levels, Ädel vs Abstrakt.

@ Nordkäppchen

You are right. I should have explained better.

Yes, that is the color code that the consultant gave me. But Ikea denied it upon request.

Unfortunately, I still don't know which color can be used to touch up small scratches. I don't want to build up a collection of paints.

I thought that since these kitchens are sold so often, someone else would have dealt with it by now.

You will probably not find a small touch-up pen in the exact matching color. For NCS there are color samples where you can compare if the shade fits. It is also possible to determine the shade with a color scanner and mix the color accordingly. I would take a drawer front to a hardware store or paint shop and compare. Maybe there is a reasonably matching white tone ready-made. Thanks for the link.
